I don't want to crash-gate but i was about to propose something of the sort.

I stand to be corrected but i think (or what i would propose) is a motion kind of effect on the images. This could be zoom in/out, or any kind of movement of the image which i think would be a cool feature resulting in adding that video effect or atmosphere.

Unfortunately, I think it has killed the MP4 support. My mp4 clicps that i had uploaded and saved in the favourites are reporting that the format is not supported (I have been using them in all my videos until now). I even tried to upload afresh but no luck. Please check to see if that is the case.

Another important aspect you need to look into at foremost is the multiple update of slides instead of updating one at a time.

At first i thought the problem was the mp4. This is because when you pushed through the update, i was at a stage of attaching an mp4 to a slide which failed to materialise.

I have done more tests and i don't know if this is only on my side or not. I have observed the following.

- It seems that whenever you make any change to a slide, the system assumes that you have added a video clip to the slide. I mean any change even adding a picture is probably been registered as a video.

- Although you can add a picture to a slide, you can't add any video - whether from the library or an upload. It just seems to start the process and then stops and doesn't give an error message.

- I tried adding an AE. It processes and then at the end hangs on gear and never finishes the process.

- The pictures that are attached when building the slides are okay but when you make change by attaching a different picture, it seems like you have added a video.

Thanks Jon for this. This fix is great as it has also addressed something i wanted to mention (the auto-animation creation during slide generation) but i thought may be this was not going to be possible because of the layouts that does not support animation but you seem to be ahead of the game. But this brings me to ask the question - why does the left and right text layout not support the animation or video. With the paning of images in the other slides with different formats, it makes the static images look very odd.

Having said that, THANKS again for the last two updates. They make the videos look very professional.

With regard to the problem on attaching videos, i think the problem was with the first and last slides only but you seem to have figured this already and solved it.
